I forgot to write up the 3.0.12 release, so I'll describe 3.0.12 and 3.0.13 together here...
I've done some work on the smc91c92 driver to handle some more card types. The Ositech Jack of Hearts cards should now work, and this may also fix some problems with Jack of Diamonds cards.
I think I've fixed all remaining problems with the 3c589 and 3c574 transceiver monitoring code. The 3c589 should no longer get stuck on 10base2 at the wrong times, and both drivers will work across suspend/resume events.
3.0.13 should build cleanly against all 2.2 and 2.3 kernel releases. Because of kernel bugs affecting various types of cards, I recommend at least 2.2.10 or 2.3.6.
I think 3.0.13 is quite stable: it doesn't appear to have any major bugs with any of the standard drivers. 3.0.14 will be out soon but (so far) has only a few minor tweaks.
